6.3.1. Adding an Endianness Test Function to the Or1ksim Library

The additional function is straightforward, since endianness is a compile time constant in the Or1ksim ISS.

```
int  or1ksim_is_le();
		
```
or1ksim_is_le returns 1 if Or1ksim is modeling a little endian architecture, 0 otherwise. It is needed to ensure the payload is packed with the correct byte ordering.

This function is a standard part of the Or1ksim 0.3.0 and Or1ksim 0.4.0 libraries.
